-Subject: x86/smpboot: Fix CPU #1 boot timeout
-Origin: https://git.kernel.org/linus/fcafddec4e78a7776db4b6685db6b2902d4300fc
-Bug-Debian: https://bugs.debian.org/802464
-
-The following commit:
-
-  a9bcaa02a5104ac ("x86/smpboot: Remove SIPI delays from cpu_up()")
-
-Caused some Intel Core2 processors to time-out when bringing up CPU #1,
-resulting in the missing of that CPU after bootup.
-
-That patch reduced the SIPI delays from udelay() 300, 200 to udelay() 0,
-0 on modern processors.
-
-Several Intel(R) Core(TM)2 systems failed to bring up CPU #1 10/10 times
-after that change.
-
-Increasing either of the SIPI delays to udelay(1) results in
-success. So here we increase both to udelay(10).  While this may
-be 20x slower than the absolute minimum, it is still 20x to 30x
-faster than the original code.
